It seems you could be right about nvidia I reckon it is the nouveau driver. I decided to purge all nvidia drivers, blacklisted nouveau and installed the latest nvidia driver from nvidia. So far no problem, Xorg.0.log is good as is kernel log.
However system log is showing: gdm-binary[899]: WARNING: Unable to find users: no seat-id found gdm-session-worker[1172]: GLib-GObject-CRITICAL: g_value_get_boolean: assertion `G_VALUE_HOLDS_BOOLEAN (value)' failed. These warnings show up in the daemon log also. So it seems there must be a problem related to gdm -- Computer fails to completely boot hangs at tty login https://bugs.launchpad.net/bugs/579764 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers-180 in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
